Bump `transformers` and `sentence-transformers` lower bounds in `langchain-huggingface` to resolve a dependency conflict with `huggingface-hub` 1.x. The existing constraints allowed `huggingface-hub>=0.33.4,<2.0.0` (so hub 1.x is valid), but `transformers` 4.x requires `huggingface-hub<1.0` — causing the pre-release CI job to fail when `uv pip install --force-reinstall` resolved hub to 1.5.0 while leaving `transformers` at 4.56.2. Breaking change for users on transformers 4.x or sentence-transformers<5.2.0 who install langchain-huggingface[full].

Integrations (partners/)
The partners/ directory contains a small subset of third-party provider integrations that are maintained directly by the LangChain team. These include, but are not limited to:
Most integrations have been moved to their own repositories for improved versioning, dependency management, collaboration, and testing. This includes packages from popular providers such as Google and AWS. Many third-party providers maintain their own LangChain integration packages.
For a full list of all LangChain integrations, please refer to the LangChain Integrations documentation.
